As for the rest, the .trash is for those that use the filemanager. If you delete this you may run into problems using that feature. Again, I advise against deleting this folder, but regularly remove the files within.
etc tmp mail and the rest are best left where they are. These are used for anything from email to statsistic programs such as webalizer, awstats, etc.
Good rule of thumb is, if you set up an account, and those folders are there. They are best left where they are. No harm done.
